IMPROVEMENT' INYPARLOR OVEN-STOVES.

`Specification forming part of Letters Patent No. 215,467,` dated May 20, 1879; application led 4July 1s, 187s.

To all whom it may concern: Be it known that I, JAMES A. LAWSON, ofthe city of Troy, county of Rensselaer, and State of New York, have invented a new Improvement in Constructing Parlor Oven-Stoves, of which the following is a specication.

My invention relates to a manner of arranging a culinary attachment consisting of aboilerhole top, an oven, and warming-closet upon the rear of what is known as a parlor heatin g-stove;7 and the object is to better adapt it to perform certain culinary operations, and at the same time the ordinary heating purposes for which such stoves are designed.

My invention consists in combining or arranging an oven and a warming-closet at the rear of a parlor heating-stove, with certain iluesand dampers, capable of directing and controlling the products of combustion in a manner hereinafter to be fully shown and eX- plained; and also an ascending flue between the warming-closet and the stove, connecting with the liuc between the oven and warming-closet, to further heat the latter by means of the heated gases after they have made the circuit of the base and are passing to the exit.

In the accompanying drawings there are four gures illustrating my invention, in all of which like reference-letters are used to designate the same parts.

.lower dampers, also the horizontal iiue between the oven and warming-closet, and the ascending flue back of the oven and leading to the exit. Fig. 4 showsa vertical section of the culinary attachment connected with the return-line in the base of the stove, and taken on the line s r of Fig. 1, in which the top iue, over the oven and its damper, is illustrated; also the rear ascending vertical exit-Hue, to-

make the circuit of theoven before heating thev stove-base, or to complete the heating of the oven and warming-closet after having made the circuit of the base when the upper damper-is closed.

The various parts of the device are thus designated by letter-reference in all vthe illustrations in which they are shown-thecombustionchamber of the stove at B, thestove-base at D, the oven at O, the warming-closet at C, the exit at E, and the boiler-hole top at A. The eXterior walls of the culinary attachment, which unite it with the stove are designated at W W. The ascending flues, which connect with the combustionchamber of the' stove and open into the top iiue over the oven, are shown at d d', and the descending iiue, which connects with the top oven -lue and the baselues of the stove, at d" d". rIhe top oven-flue is shown at 61,and the rear ascending flue back of the oven connecting with the exit at d4, and the horizontal flue between the oven-bottom and warming closet top is designatedat d5. The damper in the top oven-nue is shown at J', and the damper formed in the horizontal ilue beneath the oven and above the warming-closet at J. The 'ascending flue between the stove and warming-closet, and connecting the baseflues of the stove with the horizontal flue between the oven and warming-closet, is shown at d6.

The operation of the device is as follows: The heat and gases passing through the opening S from the combustionchamber of the stove rise into and through the two hues d d',

vand pass into the top Oven-due, cl", and to the exit E if the damper J is open. When this latter is closed and the lower damper, J, is open, the heat and gases under a draft inlluence pass down through lthe vertical fines d" d into the horizontal flue d5, and thence through the rear vertical flue, d4, to the exit, thus heating the oven bottom and sides and the top of the warming-closetat the same time. When the dampers J and J areboth closed the heated air and gases produced by the fire are compelled to pass down through the vertical lues d" el into the base-fines of the stove, to return to the ascending ue d6, arranged in part between the descending Ilue d and the Warming-closet, andin part between the warm ing-clQset and stove, this ascending flue d6 connecting with the horizontal Iiue d5 back ofthe damper J', and thence to the rear exit ue, thusl heating the Warmin g closet when the base-lines of the stove are in use.

I am well aware that various arrangements of iues-aud dampers have before been made with respect to ovens and closets located in rear of stoves that such lues about or around the said ovens and closets have been connected with the lues in the stove proper; and that my invention herein only consists in combining a Warming-closet with an oven in such a manner, as applied to a heating-stove, that the oven and Warming-closet shall be heated by an intermediate horizontal ue when the basefl'ues of the stove are not used, and when they are used that the warming-closet shailfbe additionally heated by an ascending flue between it and the stove, as well as by the horizontal intermediate iiue before named.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination with a parlor heatingstove, a culinary attachment joined at the rear thereof, said attachment consisting of a boilerhole top, a top oven-flue leading to the exit,

Van oven, and a Warming-closet arranged below ascending exit-flue at the back of the oven, v

combined and constructed toheat the several parts when the flue-damper J is closed, and in the manner herein described and set forth.

2. In combination with a parlor heatingstove, a culinary attachment joined at the rear thereof, said attachment consisting of the boiler-hole top A, oven O, and Warming-closet C, provided with the top oven flue, d, and damper J the ascending fines d d', the descending lue d, connecting with the base D, the ascending lue d6, connecting the base with the horizontal ue d5, back ofthe damper J and the ascending eXitilue (Z4, back of the oven, arranged to heat the oven and warmin gcloset when the dampers J and J are closed, as herein shown and described.
